加法游戏
因为最后两个也要被削掉，所以当成有n+2个数，分别为0位置和n+1位置，他们的主攻击力和次攻击力都为0即可

#include<cstring>
#define N 210
using namespace std;
int t,n,a[N],b[N],f[N][N];

int main()
{
    scanf("%d",&t);
    for (int q=1;q<=t;q++)
    {
	printf("Case #%d: ",q);
	memset(f,127,sizeof(f));

	for (int i=1;i<=n;i++)
	    scanf("%d",&a[i]);
	for (int i=1;i<=n;i++)

	for (int i=0;i<=n+1;i++)
	    f[i][i]=a[i],f[i][i+1]=0;

    }
    return 0;
